Piping

•Never mount the product upside down.

•The straight piping length shall be 8 cm or longer.

Otherwise, if a straight section of piping is not installed, the accuracy

varies by approximately ±2%F.S.

•Avoid sudden changes in the piping size on the IN side of the product.

•Do not release the OUT side piping port of the product directly to the

atmosphere without the piping connected. If the product is used with

the piping port released to atmosphere, the accuracy may vary.

Flow directionOUT sideIN side

Restrictor8 cm or longer

Piping for the One-touch fitting

•Accuracy can vary approximately

±2% when tubing other than the

recommended tubing is used.

•Insert the tube all the way into the

fitting so that it cannot be pulled out.

•Insertion with excessive force can

cause damage.

•Ensure there is no leakage after

piping.

•Use the product within the specified

operating pressure and temperature range.

Refer to the operation manual on the SMC website

(URL http://www.smcworld.com) for more information about safety

instructions.

Reference conditionindicator

OIndicates the reference condition selected. LED is ON(red) when standard condition is selected.

Piping for the metal attachment

•Tighten to the specified torque. Refer to the table below for the

required torque values.

•Use a suitable spanner for the appropriate torque. Do not use a

spanner 40 cm or longer.

•If the tightening torque is exceeded, the product can be broken.

If the tightening torque is insufficient, the fitting may become loose.

•Avoid any sealing tape getting inside the flow path.

•Ensure there is no leakage after piping.

•When mounting the fitting, a spanner should be used on the metal

part (attachment) of the fitting only.

Holding other parts of the product with a spanner may damage the

product.

Specifically, make sure that the spanner does not damage the

connector.

3 step setting mode

In this mode, only the set values can be input, in just 3 steps.

Use this mode if the product is to be used straight away, after changing only

the set values.

Default settings

When the flow exceeds the set value [P_1], the switch will be turned ON.

When the flow falls below the set value by the amount of hysteresis [H_1]

or more, the switch will turn OFF.

If the operation shown in the diagram below is acceptable, then keep

these settings.

Wiring

Connection

•Connections should only be made with the power supply turned off.

•Use a separate route for the product wiring and any power or high

voltage wiring. Otherwise, malfunction may result due to noise.

•Ensure that the FG terminal is connected to ground when using a

commercially available switch-mode power supply. When a switch-

mode power supply is connected to the product, switching noise will

be superimposed and the product specification can no longer be met.

This can be prevented by inserting a noise filter, such as a line noise

filter and ferrite core, between the switch-mode power supply and the

product or by using a series power supply instead of a switch-mode

power supply.

Connecting/Disconnecting

•When mounting the connector, insert it

straight into the socket, holding the lever

and connector body, and push the

connector until the lever hooks into the

housing, and locks.

•When removing the connector, press

down the lever to release the hook from

the housing and pull the connector

straight out.
